Hi there, Im using your keyboard on mobile screen, so I split it in two keyboards due to screen size.

When I'm turning note labels on or off, only note labels on bottom keyboard will be turned off or on, only after app is restarted, will both keyboards labels be turned of or on, how could I change that so that I can turn labels on both keyboards?
